The head of the white supremacist Aryan Brotherhood of Texas has pleaded guilty to a racketeering conspiracy that included murder, kidnapping and drug trafficking.

Larry Max Bryan, 52, who goes by the name 'Slick' pleaded guilty on Friday before U.S. District Judge Sim Lake in Houston.

Under federal law, Bryan could be sentenced to up to life in prison. The plea agreement calls for prosecutors to recommend the 52-year-old be sentenced to no more than 25. Sentencing is set for Oct. 7.

Bryan was among nearly three dozen people allegedly affiliated with the Aryan Brotherhood who were charged in a sweeping indictment unsealed in 2012.

Dozens of defendants have been convicted in an ongoing federal investigation of the military-style gang founded in Texas prisons in the 1980s to offer protection to white inmates.
